Hi Kepp27, nice tutorial, very orginized.however i still got a problem, i keep getting the following message on CMD: "could not find or load main class code.SimpleRead". even after i set the classpath to "C:\Program Files (x86)\Java\jdk1.8.0_102\jre\lib\ext\comm.jar".i double checked the pathes of the files i needed to put in the jdk directory and they are all where they suppose to be.can you help me please?

hello. many thanks for the links.i tried to use the grub function made by the russian but the java code produces nothing (im using eclipse 32bit and jre 32bit as instructed.). i think im using the port wrong... should i change the COM9 portion in the code for something else than COM3?thanks in advance for your help, im really clueless about what to do next.
